Re: A problem in embedded SQL

Marvin,

Since you have a small program that exhibits this behaviour why not post the whole source, plus the statements to create the table and let us try it on our own systems?

The only thing I can think of if all that you say is true is that you perhaps have a missing PTF. I do remember one instance a while back when there was an issue with embedded SQL but it was quite a long time ago.

I debug the program and step by step watch it execute. The prepare statement has no errors. The Open has no errors. But the fetch fails to find the record I know it should. I copy/paste the sql statement into STRSQL and it finds the record. I don't understand why the two are behaving different.

Thanks,

Marvin

There are a lot of responses to this that I didn't read and if someone has already mentioned this, I apologize for the repeat. I have seen this same weirdness when I forgot to close the cursor on a previous run but I don't remember any specifics like if I was in debug or anything like that. I also don't remember if the prepare or open failed, only that I got the SQLCOD =
100 on the fetch and I knew the data was there. When I logged off and back on and got my data on the next run.

Subject: A problem in embedded SQL

I am working on a program that is supposed to return a data element when the user requests it is using two parameters.

The problem is in the RPGLE (running under 7.1) the sql statement returns EndOfData when I attempt to use the program with parameter that I know is there. But if I take the sql statement and use interactive sql, it works and selects the correct record.

I don't understand what the difference is between the two methods.

The sql statement is:

SELECT ipol#
FROM commcmtp
join commitmp on ccomp=icomp
and ipol# = cpol#
and cseq = iseq
and iccode like 'EAPP%'
and crecid = 1
and ccomm like '%81925B%'

In the RPGLE, it is a prepared statement that is okayed by the prepare statement. It is okayed by the open statement. But the fetch statement returns EndOfData.

Taking the same sql statement and executing it in interactive sql, it works properly and returns the expected data element.

Can anyone give me a clue why it doesn't work in RPGLE?

Marvin
